Title: Surface acoustic wave element, its design method and signal receiver and communication system using the same
Inventor: EGUCHI TADASHI
IPC: H04J13/00
Filed: 1994-02-28
Abstract: PURPOSE:To obtain a high coupling efficiency by providing a shape corresponding to an angle dependency of a speed of a surface acoustic wave depending on a direction when the surface acoustic wave propagates on an isotropic piezoelectric substrate for an input electrode and to concentrate the surface acoustic wave to a narrow range. CONSTITUTION:A guide path 14 is an ideal path guiding a surface acoustic wave to a guide path end face (origin position) as if it were almost regarded as a point wave source. Part 12 of a wave front of a surface acoustic wave is outputted from an end face of the guide path 14. The shape of an interdigital input electrode 11 is obtained by calculating the behavior of the surface acoustic wave outputted from an end face of the guide path 14 and propagating on an isotropic piezoelectric substrate. Since the distance and angle of each observing point from a wave source are found out by setting observing points to be a mesh, the distance vector and the wave number vector are obtained and the complex amplitude is calculated. Contour lines of the complex amplitude indicate the wave front. Thus, the shape of the interdigital input electrode 11 is decided corresponding to the shape of the surface acoustic wave spread from a point wave source obtained in this way.

Abstract: PURPOSE:To prevent a floating surface from being damaged by reproducing an air bearing even when dust, etc., is stuck on the floating surface by providing a shape memory floating surface formed with a shape memory material at least at a part of the floating surface, connecting a heating means, and floating a head slider in a short time. CONSTITUTION:A time when a disk 2 is brought into contact with a floating head slider 4 can be shortened by heating the shape memory floating surface 20 by the current controller 15 of the heating means 14, and expanding the area of the floating surface of the floating head slider. Meanwhile, the slider 4 should be floated with a prescribed floating quantity hN over the plane of the disk 2 rotating at prescribed revolution speed VN to perform the write and readout of data on the plane of the disk 2. When the floating surface is continued to be heated, the floating quantity exceeds hN. However, since the area of the floating surface is returned to an initial value by stopping heating, conditions for VN and hN can be simultaneously satisfied.

Title: Video signal reproduction circuit
Inventor: TOEDA HIROSHI
IPC: H04N5/93
Filed: 1987-02-14
Abstract: PURPOSE:To widen the band of the reproduced frequency characteristic of a video signal without making the inductance and the parallel capacity of a video head small by giving a positive feedback to the input side of a preamplifier inputting the output of the video head through a capacitor. CONSTITUTION:The positive feedback is applied to the input side of the preamplifier through the capacitor Cx. Thus, the capacity component (parallel capacity C) of the input side impedance of the above mentioned amplifier, including the stray capacity of the video head, is made to be equivalently zero or reduced. When the capacity C is equivalently made to be zero, the resonance does not occur, and even when the capacity C is not made to be perfectly zero and is made to decrease, a resonance frequency is increased in proportion to it, and moreover, since the resonance comes to be easily damped, the resonance damping can be performed by the input resistance portion Ri of a usual preamplifier, and the desirable widening of the band can be realized.

Title: Equipment for incinerating waste liquid
Inventor: IMAMURA MITSUO
IPC: F23G7/04
Filed: 1989-02-13
Abstract: PURPOSE:To reduce the use of auxiliary fuel in quantity by providing a means for vaporization for completely vaporizing waste liquid in a setup to incinerate the vapor of waste liquid from the means of vaporization. CONSTITUTION:To a spray-vaporizing tower 1 for vaporizing waste liquid, waste liquid sprays 3 are attached and a waste liquid-conveying pipe 2 is connected. The vapor of waste liquid, vaporized by the spray-vaporizing tower 1, is conveyed by a vapor duct 5 to a gas fan 6. On the downstream side of the gas fan 6 is installed a dust collector 7, whereby inorganic solid matter which has been contained in the waste liquid and is carried by its vapor as the waste liquid vaporizes is eliminated. The vapor, from which inorganic solid matter has been eliminated by the dust collector 7, is conveyed to a catalytic combustion device 8 and burned at a catalyst layer 9 for combustion. The exhaust gas produced by the combustion in the catalytic combustion device 8 is discharged to a stack 17; part of the exhaust gas is conveyed by a combustion gas-circulating duct 18 to the spray-vaporizing tower 1 so that the heat retained by the combustion gas is utilized for the vaporization of waste liquid. Thus waste liquid is first completely vaporized and then the vapor is incinerated; waste liquid can be disposed of by combustion at relatively low temperature, hence lessening in the quantity of auxiliary fuel required. Moreover, the vaporization of the waste liquid utilizes the heat retained by exhaust gas from the combustion. Thus the use of auxiliary fuel is reduced in quantity as a dual effect of the procedure.

Title: Float valve
Inventor: KOIKE TADASHI
IPC: F16T1/24
Filed: 1989-02-09
Abstract: PURPOSE:To reduce the frictional resistance when a float is raised to zero and to provide a high valveopening force by means of an increased wedge force by a method wherein a magnet repelling the magnet member of a float is mounted to a contact part between the float and a valve casing or a lever. CONSTITUTION:A float 11 is raised along with a rise in a level in a valve chamber 4, and approaches a lever 13 and a protection cover 18. However, it is prevented from contact therewith through the reaction forces of magnets 3, 16, and 17. Further, when a level is raised, buoyancy of the float is increased, and buoyancy is exerted as a wedge force on the lever 13 without contact of the float with the lever. This constitution enables reduction of frictional resistance to zero and permits utilization of the whole of buoyancy of the float 11, and prevents hooking of the float.
